, I 1 VENDING MACHINE.

Application filed October 6, 1924. Serial No. 741,825.

The object of the present invention is to provide a vending machine for small units and so designed as to be adapted for the backs of theatre seats for dispensing penny units of confections or other articles. The characteristic of the device is the ejection of the individual units from the bottom of a stack, in conjunction with novel means for shutting off access to the stack from the discharge slot. The invention also comprises a novel form of means for automatically shutting off the coin slot when the device is emptied. Other features of the invention will be hereinafter set forth. V

The invention will be described with reference to the accompanying drawings 1n which- Figure 1 is an elevation of the device, partly broken away, the parts being in their position prior to an ejecting movement.

Figure 2 is a view similar to Fig. 1, showing the position of the parts at the end of an ejecting movement.

Figure 3 is an elevation of the device showing the parts in their position after the device has been emptied, the coin slot being closed.

Figure 4: is a horizontal section on the line 44, Figure 8, looking in the direction of the arrow. I

Figure 5 is a vertical section on the line 5, Figure 3, looking in the direction of the arrow.

Figure 6 is a detail sectional plan view of the coin support, the section being on the line 66, Fig. 5, and also showing in dotted lines the horizontal portion 12 of the finger lever.

The device is shown embodied in a rectangular casing A having a vertical removable chamber B comprising the side walls 1, 1 and rear wall 2, for the reception of a stack of the units 3 to be vended. Casing A is pro vided with a discharge outlet a. The lowermost of the stack of the units rests upon a platform or table 4 formed as a part of cam plate 5 having a cam slot 5", the cam plate being pivoted at 6 upon the inner rear wall of the device.

Cam plate 5 and platform 4 are operated by a lever 7 fulcrumed at 8, the lever having at its lower end a stud 9 which enters cam slot 5*. The cam slot is so designed that when the lever is in its normal position, as shown in Figure 1, platform 4 is held elevated above the top of the discharge outlet a, and when the lever is swung to the right, platform 4 is lowered to the position shown in Figure 2. In the initial position of the lever as shown in Figure 1, its extreme lower end holds an angularly bent finger 1.0 adjacent the side of the lowermost unit 3, and as the lever is swung to the right thus lowering platform l, the said lowermost unit is moved by finger 10 to the right until it is ejected partially out of discharge outlet (1, as shown in Figure. 2. When the lever 7 is swung to the left and back into initial position, finger 10 passes to the left of chamber B and thus the succeeding unit 3 is permitted to fall onto table 4: and in register with the linger.

The coin control means for operating lever 7 will now be described: Fulcrumed upon stud 8 to the rear of lever 7 is the finger lever 12 having a projecting arm 12 engaged by spring 13 which at its lower end is connected to a projection 14 carried bya wall of chamber B. This spring normally serves to hold finger lever 12 in its right hand position as shown in Figure 1. Finger lever 12 is bent at right angles to form the horizontal portion 12 and thence extends upwardly in register with the edge of top wall m of the device, and thence is bent over to form a finger piece 15. 1

It will be noted that the upper end of lever 7 projects above the horizontal portion 12 of finger lever 12, passing through an opening 15 and normally in engagement with the wall of said opening, as shown in Figure 4.

Secured upon the back wall of the case A is a coin support 16 having the laterally projecting ledges 17 to support a coin inserted through the coin slot 18 formed in the upper wall (1* of the device. hen the coin is inserted in the slot 18 is passes downwardly until it meets a depressed Wall 17 and rests thereon, also against shoulder 20 of horizontal portion 12 of the finger lever and adjacent projecting finger 1.6 formed as a part of said horizontal wall 12 of finger lever 12. The coin, at its margin, also is in proximity to the end '1' of lever 7. When the finger piece 15 is moved to the left from its position shown in Figure 1, finger 16 contacts with the coin and carries it forcibly against end 7 of lever 7 swinging said lever on its fulcrum 8 and carrying the lower end of the lever to the right. As the lower end of lever 7 moves to the right, its end 10 comes into contact with the lowermost unit 3 and simultaneously therewith table 4 is lowered by the action of stud 9 on cam 5 so that when the end of the unit approaches the outlet at, the right hand end 01" the table is lowered below said outlet and a continued movement of finger projects the unit partly through the discharge outlet, as shown in dotted lines in Figure 2. Upon release of the linger piece 15, the spring 13 will carry finger lever 12 back to its original position, as shown in Figure 1, and inasmuch as the upper end of lever 7 isin register witha wall of the open ing-15 or the linger lever, it will be seen that the action of the spring also carries lever? back to its initial position, as illustrated in Figure 1.

The length of the ledges 17 may be such that the coin will rest thereon and not be permitted to drop during the movement of the levers untilthe unit engaged by finger '10 has been projected part way through the dis charge openinga. Upon a complete movement to the left or" the linger piece 15, the coin will be carried past the ledges 17 and upon release of the finger piece, the coin, theretotore gripped between linger l6 and the end 7* or lever 7, will drop downward into the cup C resting on the top of the stack of units 3.

The finger 16 is so positioned to strike the coin at approximately its centre. There coin of normal width will initially rest on the depressed edge 17* of the left hand leg of the coin support, whereasa-disk thinner than the coin will pass between the two legs of the coin support and down intogthe cup C. A disk smaller than the'coin will not be supported by depressed edge 17 X and will pass=through the coin support. 7

The mechanism for closing the coin slot, and preventing operation of thevd'evice when on coin support 16*.

emptied of the units 3 will now be described.

By reference to the drawings it will be seen *in the horizontal portion of 12 of finger lever '12, the latter lever is held, by the action of spring 13, in the position illustrated in Figures 3 and 4-. In such position finger 16 lies immediately below the coin slot and a coin cannotpass downward through the slot beyendthe top ofsaid linger 16'. Movement of "linger lever 12 to the left from the position illustrated in Figure 4, against'the tension of spring 13, will not alter the condition, because the horizontal Wall 12 will continue. to bar a coin against passage through the coin slot to its normal position It will be understood that 'variousmodifications may be "made in theform and arrangement of the elements comprising the de vice without departing from the spirit of the invention, what I claim and desire to secure by "Letters Patent being as follows:

A coin-control vending machine compris ing acasing having a vertical wall and a dis charge outlet at its lower end, a plate piv- 'oted to tlie'vertica'l wall and havingat its lower end a finger for ejecting lowermost articles from the stack, table pivoted to the casing wall and normally shuttingoli the stack of articles from said opening, the table having a member extending adjacent and pa 'allel with the casing wall and formed with a cam, and a cam operating member carried "by the said 7 plate and engaging said cam whereby the table is pivotally lowered during an ejecting movement.

In testimony whereof, I have signed my name to this specification.
